The Mid-Back Ergonomic Mesh Office Task Chair (model MB-MESH-WF-625BL, unbranded) features a coordinated neutral color palette of white, blue, and grey for a streamlined, professional visual profile that complements a wide range of interior design schemes. Its compact, balanced layout is configured for individual task use, with a five-prong base that provides stable support without excessive floor footprint, and fixed loop armrests positioned to align with standard seated typing postures. The chair is built with durable, purpose-selected materials for long-term regular use. Its backrest uses a white glass-fiber reinforced polypropylene support frame, upholstered in blue tensioned breathable polyester mesh shaped to include a contoured dual-zone integrated lumbar support zone for targeted lower back comfort. The seat uses a high-density molded polyurethane foam core upholstered in grey woven polyester fabric, with a foam density of 60 kg/m³ and 60% rebound rate to maintain supportive cushioning over extended use. Fixed white polypropylene loop armrests are secured directly to the seat and back frame for rigid forearm support, while a black painted Class 3 hardened steel gas lift connects the seat to a white molded nylon five-star base. Mobility is delivered via 60mm diameter dual-wheel black PU soft casters, and a 2.5mm thick stamped steel chassis houses the tilt control mechanism with user-accessible tension adjustment. Core functional features include full 360° swivel rotation, 100mm of pneumatic seat height adjustment controlled via a right-side under-seat lever, and synchronized backrest tilt that locks in place at a maximum 125° recline angle. An under-seat knob lets users adjust tilt tension to match individual weight preferences, while the dual-wheel casters enable smooth multi-directional movement across hard floors and low-pile carpet. The 60mm thick seat cushion and breathable mesh back reduce heat buildup during prolonged seated tasks, and the chair supports a maximum user weight of 120 kg, with a Martindale abrasion resistance rating of 50000 cycles for the seat upholstery. At its maximum adjusted height, the chair measures 625 x 620 x 1075 mm, with a 470mm wide, 580mm tall backrest, 490mm wide, 460mm deep seat, 190mm armrest height above the seat surface, and 620mm caster-to-caster base width. It has a net weight of 14 kg. This chair is well-suited for a broad range of public and commercial work environments. It fits seamlessly into open-plan office workstations, where its compact footprint and height adjustment align with standard desk configurations, as well as home office spaces, where its understated colorway and quiet, floor-friendly casters suit residential settings. It performs reliably in conference and meeting rooms, where its fixed armrests and mid-back structure encourage upright, engaged posture for group discussions, and in high-turnover co-working shared spaces, where its durable mesh construction and swivel function accommodate frequent user changes. Its lightweight, mobile design also makes it easy to reconfigure for staff training room layouts, while its professional aesthetic and breathable support work well for extended seated shifts in reception and admin areas.
